POST request returns 500 cannot update item

Hello,

I am trying to use POST / PUT to update fields for products. However I am running into issues.

The situation:

• I have a post type called ‘product’
• I have an ACF field called ‘connected_suppliers’
• I am using this request with Postman: https://dev.site/wp-json/acf/v3/product/13/?connected_suppliers=21

The POST request however is giving me:

{
    "code": "cant_update_item",
    "message": "Cannot update item",
    "data": {
        "status": 500
    }
}

When I start debugging, I kind of get stuck at prepare_item_for_database() It looks like $request over there has no params under POST.

The WP_REST_Request contains this:

        )

    [parsed_json:protected] => 1
    [parsed_body:protected] => 
)

By now I am totally and utterly in the dark, because I have no idea on how to proceed from here.

I really hope anyone can help me out.

Thanks.
